Some readers will hold that no study of human efficiency can be complete without an analysis of religious efficiency. This subject has been omitted for the most part for various reasons The last five chapters are incidentally a discussion of the limitations of human powers, hence imply a theory of man's religious nature. Strictly speaking, the question of moral efficiency, considered in the last chapter, underlies and include: the religious problem. The present study is prevailingly psychological, and it is impossible to consider religious matters in a satisfactory manner without passing beyond even the implies philosophy of efficiency which at many points in the investigation grows out of and leads beyond the psychological inquiry. Finally, I have omitted the question of religious efficiency because in another volume, The Philosophy of the Spirit, I have analysed man's spiritual nature at length The purpose of the present discussion is to direct attention to practical results. He who through study of psychological principles makes himself more efficient in the field in which he happens to be engaged, should be able to turn to the religious field and labour more effectively. What is now needed in the religious world is practical service in matters close at hand. Of theories of efficient in a doctrinal sense we already have enough.
